.IITTORNEY United States Patent O 2,806,626 TABLET BOXES Robert Nyden,Manhasset, N. Y. Application April 15, 1955, Serial No. 501,580 4Claims. (Cl. 220--31) The present invention relates to containers suchas pivoted cover tablet boxes and the like wherein the cover isunlatched by pressing on the rear portion of the cover.

It is the principal object of the invention to reduce the cost ofmanufacture by reducing the quantity of material necessary to produce acontainer having the same carrying capacity as the containers in presentuse and by reducing the time required to produce said container.

It is another object of the invention to provide novel pivotalconnections between the body and cover. which prevent the cover frombeing accidentally disconnected from the body of the container andpermit the cover to assume full open position without causing thecontainer body to tip-over backwards and thereby facilitating thefilling of the container body with tablets and inserting an instructionfolder over the tablets.

lt is another object of the invention to arrange the front wall of thecontainer body to prevent spilling of the tablets from the containerbody when the cover is opened by pressing on the rear portion of thecover and retain the instruction folder within the container body uponthe initial closing of the cover to complete the packing operation.

Other objects and advantages of the invention will be set forth in thedetailed description of the invention.

In the drawing accompanying and forming a part of this application:

Figure 1 is a top plan view of the container forming the embodiment ofthe invention and with the cover closed;

Figure 2 is a front elevational view of the container with the coverclosed.

Figure 3 is a sectional view, on an enlarged scale, taken on the line3-3 of Figure 2 looking in the direction of the arrows;

Figure 4 is a side elevational view of the container, on a reducedscale, with the cover fully open and the body in position to receivetablets from a filling machine and permit insertion of the instructionfolder;

Figure 5 is a view similar to Figure 3 but showing the front portion ofthe cover raised from the container body by pressing on the rear portionof the cover;

Figure 6 is a fragmentary sectional view taken on the line 6-6 of Figure3 looking in the direction of the arrows to show the relationshipbetween a fulcrum indentation in a side wall of the cover and the edgeof a side Wall of the container body;

Figure 7 is a fragmentary sectional View taken on the line 7-7 of Figure3 looking in the direction of the arrows to show the pivotal connectionbetween the cover and the container body; and

Figure 8 is a side elevational view of the container showing the coverbeing closed after the tablets and instruction folder have beenassembled in the container body to illustrate the function of the frontwall of the container body in retaining the instruction folder in thecontainer body.

The embodiment of the invention comprises a container body including abottom wall 9 having an integral front Mice wall 10, integral side walls11 and an integral rear wall 12. A cover is pivotally connected to thebody to telescope over the side walls of the body. Said cover comprisesa flat top wall 13 having downwardly curved marginal portions 14integrally connecting the top wall 13 to a front wall 15, side walls 16and a rear Wall 17.

The edges of the body walls 11 and 12 and the cover walls 15, 16 and 17are straight and extend in the same plane, respectively. The heights ofthe container walls 11 andy 12 are the same and the heights of the coverwalls 15, 16 and 17 from the curved portions 14 to the edges of saidcover walls are the same but slightly less than the heights of thecontainer Walls 11 and 12. To prevent tablets T from spilling whenpressure is applied to the rear portion of the cover and to retain aninstruction leaflet or folder F in the container body when closing thecover after the packing operation is completed, as shown in Figure 8,the front wall 1t) is arranged with a center portion of increasedheight, as shown at 18 in Figures 2, 3, 4, 5 and 8. The end portions ofthe body front wall 1@ are of the same heights as the heights of thebody walls 11 and 12, as shown at 19 in Figure 2.

The cover is pivotally connected to the body by a pair of shiftinghinges comprising opposed circular indentations 2@ in the body sidewalls 11 near the body rear wall 12 and midway of the edges of the bodyside walls 11 and the body bottom waii 9, as shown in Figures 3, 4, 5, 7and 8. The indentations 2G are engaged by trunnions 21 of invertedV-shape formed from the material of the cover side walls 16 at the edgesof said side walls and tapering inwardly of said cover side walls to apointed portieri 22, as shown in Figure 7. The heights of the trunnions21 from the edges of the cover side walls 16 to the angle of the V isapproximately equal to the radius of the inner circle of theindentations 20 and the distance between the ends of the sides of theinverted V of the trunnions 21 is slightly less than the diameter of theinner circle of the indentations 2i), as shown in Figure 3, to permitthe trunnions 21 to shift within the indentations 2? when pressure isapplied to the rear portion of the cover and the cover is moved to openposition, as shown in Figures 4, 5 and 8. The dimensions of thetrunnions 21 relative to the dimensions of the indentations 20 togetherwith the angle of the V of the trunnions 21 will prevent accidentaldisengagement of the cover from the body by assuring that either or bothof the angle of the V and the ends of the sides of the V of thetrunnions 21 are in engagement with the inner circumference of theindentations 26 in any position of the cover.

When pressure is applied to the rear portion of the cover, the frontportion of the cover is raised or moved from the front portion of thebody by providing fulcrums on the cover side walls 16 in the form ofopposed indentations 23 of semi-circular shape in the material of saidiside walls spaced from the edges of the side Walls 16 and the curvedmarginal portions 14 of the cover top wall 13 and between the trunnions21 and the cover front Wall 15 and nearer to the trunnions 21 than thecove'r front wall 15, as shown in Figures 3, 4, 5 and 8. The fulcrumindentations 23 are formed in the cover side Walls 16 so that the flatdiameter portions of the semi-circles of the fulcrum indentations 23 aresevered from the side' walls 16, as shown at 24 in Figure 6, andextended inwardly beyond the body iside walls 11 to provide sharp edgesto engage the edges of the body side walls 11, as shown at 25 in Figure3, whereby when pressure is applied to the rear portion of the cover,the body side Walls 11 will not buckle and the indentations 23 will notslip over the body side walls 11. In the closed position of the cover,the cover is supported by the engagements 25 and the body front wallportion 18 engaging the curved portion 14 at the front of the cover topwall 13, as shown in Figure 3.

at the same time thereby reducing the time required to f produce thecontainer.

As is usu-al in this type of container, the cover is retained againstaccidental opening by latching means 26 on the front walls 1-0 and 1S,and said latching means is released byV pressure on the rear portion ofthe cover. After the latching means is releasedv in this manner, thecover is moved to full open position in the usual manner.

Having thus described my invention, I claim:
